Q1: What is the primary chemical class of POLYSYNTHREN Blue RLS 45?
A: POLYSYNTHREN Blue RLS 45 is an organic pigment based on a copper phthalocyanine structure, offering high chromatic strength, excellent lightfastness, and good thermal stability typical of this pigment family.
Q2: Is this pigment suitable for use in food-contact plastics?
A: POLYSYNTHREN Blue RLS 45 is designed for industrial applications and is not pre-approved for direct food-contact use. Customers must verify regulatory compliance—including local food contact legislation—through full formulation testing and supplier documentation before deployment in such applications.
Q3: How does POLYSYNTHREN Blue RLS 45 perform in high-temperature polymer processing?
A: This pigment demonstrates good thermal stability and is suitable for use in polymers processed at elevated temperatures, including polyolefins and engineering thermoplastics. Performance remains consistent under standard extrusion and injection molding conditions when properly dispersed.
Q4: What is the recommended dispersion method for optimal color development?
A: For best results, POLYSYNTHREN Blue RLS 45 should be incorporated using high-shear mixing or twin-screw extrusion to ensure complete deagglomeration and uniform distribution. Pre-dispersed concentrates are also available and often preferred for consistent dosing and reduced handling variability.
